The Advanced Photon Source was commissioned in 1995 as a third generation x-ray user facility. At that time, orbit control was performed exclusively with broadband rf beam position monitors. Since then, emphasis has been placed on incorporating x-ray beam position monitors into the orbit control algorithms. This has resulted in an order of magnitude improvement in long term beam stability vertically, using x-ray bpm's on bending magnet beamlines. Additional processing will allow similar improvements horizontally, once systematic effects associated with variable insertion device x-ray beams are properly compensated. Progess to date and upgrade plans will be presented, with an emphasis on the details of the required digital signal processing.
